FIG. 1 is a front view of a user interface for a keyboard, keypad, or touchscreen showing my new design;

FIG. 2 is a right side view thereof shown removed from its environment in order to show aspects of the design that are not apparent in the FIG. 1 view, the left side is identical; and,

FIG. 3 is a top view thereof shown removed from its environment in order to show aspects of the design that are not apparent in the FIG. 1 view, the bottom view is identical.

The portions of the user interface shown in dot-dot-dash broken lines are directed to environment and are for illustration only; they form no part of the claimed design.

The evenly spaced horizontally parallel broken lines shown in various locations indicate a change in color. 

The ornamental design for a user interface for a keyboard, keypad, or touchscreen, as shown and described.
